Chelsea legend Michael Ballack has urged Eden Hazard to make his future clear.

The Belgian, who has been linked with Real Madrid, has yet to commit his future to the club, without ruling it out either.

And Ballack says the 27-year-old must not leave the club hanging.

"Eden Hazard has to decide if he wants to stay or not," he told Omnisport . "He's not only an outstanding player at Chelsea but also in the Premier League. Now, he has to decide if he wants to play at an ultimate, top club. That's what he's already communicated from time to time.

"In my opinion, he is a little bit too calm, especially at Chelsea. There, he should be more demanding and expressing of his wishes. He can do that because he is in an outstanding position. If he wants to win more titles with Chelsea, something has to happen, otherwise Eden Hazard will think about looking for another opportunity."
